Flammable liquids in motion when is transporting by pipes, is mixing, pumping, filtering, agitating or by pouring them from one vessel to another can generate static charges even if the respective pipes or vessels are bonded and earthed. Also, loads may occur if the liquid is splashes and forms a mist inside the vessel (tank, container). Accumulation of static electricity can, under certain conditions, be discharge and ignite the explosive atmosphere. In the paper are presented some aspects regarding the technical...

Because, in most cases, dust explosions cause significant damage to the environment, they can be treated as a disaster. Appropriate measures must be taken to prevent explosions. These measures are aimed at preventing the formation of explosive atmospheres, preventing the occurrence of ignition sources and limiting the effects of the explosion. Static electricity is one of the sources of ignition of the potentially explosive atmosphere of dust / air. Assessing the occurrence and the possibility of initiating discha...

Most of the time, in assessing a situation where a leakage of combustible gas is involved, the volume of the room where the release occurs and the volume of the released gas is taken into account, thus resulting in an average concentration of the fuel gas applied to the entire volume of the room. In some cases, when the source of combustible gas is close enough to the source of initiation, or when air currents converge at the location of the source of initiation carrying amounts of combustible gas, the explosive m...
